MANILA, Philippines ? Alleged irregularities in the testing and sealing of the precinct count optical scan (PCOS) machines have been discovered by the camp of Nationalista Party (NP) standard-bearer Manny Villar.

In Muntinlupa, for instance, Villar's name could not be read by the poll automated machines, NP spokesman and senatorial bet Gilbert Remulla said over the phone on Monday night.

"When the result came out after the voting, walang Villar na lumabas [no vote for Villar was counted]. Our team members voted but their Villar vote did not appear," Remulla said.

In Mindoro, Remulla said, the machines only read the name of administration bet, former Defense Secretary Gilbert Teodoro.

"Tapos sa local officials, mga taga Lakas (Lakas-Kampi-CMD) lang ang lumalabas [And among the local officials, only candidates of the Lakas appear]," he said.

Other irregularities in the testing of PCOS machines, he said, were also reported in Batangas, Makati, and Pateros.

"Hindi binabasa ang boto ng tao [It does not read the votes of the people]," said Remulla.

He then asked the Commission on Elections (Comelec) to address the problem.

"It seems that there's basis to speculations of a failure of election, after all," Remulla said.

"The Comelec has to answer to these serious charges against them," he added.
